Measurement of inclusive double-differential νμ charged-current cross section with improved acceptance in the T2K off-axis near detector
Physical Review D American Physical Society 98:1 (2018) 012004
Abstract:
We report a measurement of the flux-integrated cross section for inclusive muon neutrino chargedcurrent interactions on carbon. The double-differential measurements are given as a function of the muon momentum and angle. Relative to our previous publication on this topic, these results have an increased angular acceptance and higher statistics. The data sample presented here corresponds to 5.7 × 1020 protons on target. The total flux-integrated cross section is measured to be ð6.950 0.662Þ × 10−39 cm2 nucleon−1 and is consistent with our simulation.Ionization electron signal processing in single phase LArTPCs: Part I Algorithm description and quantitative evaluation with MicroBooNE simulation
Journal of Instrumentation IOP Science 13 (2018)
Abstract:
We describe the concept and procedure of drifted-charge extraction developed in the MicroBooNE experiment, a single-phase liquid argon time projection chamber (LArTPC). This technique converts the raw digitized TPC waveform to the number of ionization electrons passing through a wire plane at a given time. A robust recovery of the number of ionization electrons from both induction and collection anode wire planes will augment the 3D reconstruction, and is particularly important for tomographic reconstruction algorithms. A number of building blocks of the overall procedure are described. The performance of the signal processing is quantitatively evaluated by comparing extracted charge with the true charge through a detailed TPC detector simulation taking into account position-dependent induced current inside a single wire region and across multiple wires. Some areas for further improvement of the performance of the charge extraction procedure are also discussed.Ionization electron signal processing in single phase LArTPCs: Part II: Data/simulation comparison and performance in MicroBooNE

Abstract:
The single-phase liquid argon time projection chamber (LArTPC) provides a large amount of detailed information in the form of fine-grained drifted ionization charge from particle traces. To fully utilize this information, the deposited charge must be accurately extracted from the raw digitized waveforms via a robust signal processing chain. Enabled by the ultra-low noise levels associated with cryogenic electronics in the MicroBooNE detector, the precise extraction of ionization charge from the induction wire planes in a single-phase LArTPC is qualitatively demonstrated on MicroBooNE data with event display images, and quantitatively demonstrated via waveform-level and track-level metrics. Improved performance of induction plane calorimetry is demonstrated through the agreement of extracted ionization charge measurements across different wire planes for various event topologies. In addition to the comprehensive waveform-level comparison of data and simulation, a calibration of the cryogenic electronics response is presented and solutions to various MicroBooNE-specific TPC issues are discussed. This work presents an important improvement in LArTPC signal processing, the foundation of reconstruction and therefore physics analyses in MicroBooNE.Photon detector system timing performance in the DUNE 35-ton prototype liquid argon time projection chamber
